to be frank , I have difficulties to understand how it is possible that the majority of thinkers consider just this BB and photons oscillating with this GR , we have evolved in 100 years of relativity and hop gocus pocus the majority concludes that they understand the generality of the universe and its philosophy. Is it a hidden camera, we have deeper logic to add to this puzzle, and the photons alone like primoridial essence is total non sense for me. They are just photons , a tool for the universe and the luminiferous spacetime is just a part of the puzzle, so what is this prison of thought ? we are youngs at this universal scale, and how is it possible that we conclude these things about the gut, the toe, the photons, the strings, and others ? the universe is more complex than this and has so many secrets to show us. The fact to consider just the photons and their oscillations vibrations, absorptions, emissions or this or that is more than reductor considering our limitations. We can compare our knowledges at this quantum scale to our knowledges at this comsological scale, we have more than 10000billions of galaxies, and even our nearest planet we don t know it lol , it could be well if the thinkers are a little bit less persuaded to know how acts this universe because it becomes odd. We are not in a competition of knowledges, we search answers and we cannot affirm unknowns and we cannot conclude due to these limitations.
